cylinder with one fixed (adjustable) and one mobile measuring arm holder. The measuring direction
is reversible by a simple turn of the adjusting screw at the end of the instruments. This feature enables
measurements of internal and external dimensions. Clamping shaft 8H7 for dial indicator or measuring
probe (measuring range 0 - 10 mm) not included. The nominal size is set with gauge blocks, setting
rings or something similar.
